With this code, can you please improve on it and see what can be fixed. Thank you!

Transcribed Image Text:This week's project culminates in combining functionality from some past week assignments. Your job is to create a java GUI that: 1) Allows the user to enter a Runner's name, distance and time of the runner's race. Edit/Text box controls are typical for this type of functionality. 2) Using a button control, allow the user to enter the information from step #1 to a list-view style control that can display the runner's name, distance, time, and also the calculated pace (in minutes) 3) Include a button control to sort by, depending on the selection of a radio button control: a. The runner's name in A-Z alphabetical order. This changes the runner's name and corresponding distance, time & pace b. The distances in descending order (longest distance run at the top) c. The time in ascending order (shortest distance run at the top) d. The pace in ascending order (fastest pace run at the top) 4) Include a button control to save the current list view information in a csv file, comma delimited between runner's name, distance, time & pace. The name of the file can be set to a default called finalProjectRunners.txt
